Top 5 MODS For 3rd Gen Lexus IS

[@chrisc4358]

For bags, I recommend sticking to Airlift everything. Make sure to drain your tank frequently for condensation. You also have to worry about clearance not only at ride height, but at air out, which makes finding the right wheel/tire combo a pain. Yes, you can get more clearance with more camber, but then you'll be more prone to uneven tire wear. Ride quality is completely adjustable from feeling factory ride quality to full coilover like stiffness. Alignments should be done at your ride height so make sure to not drive aired up from your normal drive height for too long. Pretty sure I'm missing a lot still but those are what come to mind.

That’s wild, I remember watching this video years ago when I first got the IS. Completely forgot about the LCA bushings and JUST had to replace my front two tires. Will definitely have to get on that.

[@teraa6996]

im considering replacing the LCA bushings. But idk if my car has that problem, it's a '17 is300 f sport. what's ur car

[@Spinnywhoosh]

@@teraa6996 2016 F sport as well. I think you’ll basically know if your inner front tires start wearing out very quickly. I saw thread showing on the tires and the car doesn’t get driven very often so I knew something was up.

[@Spinnywhoosh]

@@teraa6996 I ended up going with the RCF ICA bushing. Heard they hold up much better and at $70 didn’t break the bank.

[@GR8APE69]

​@teraa6996 I'm pretty sure ALL 3ISs have the same shitty LCA bushings. I've always heard other people recommend using the OEM RCF bushings as a replacement. Not sure if the aftermarket options boast the same quality as the OEM RCF bushings or not. I'm honestly skeptical that any aftermarket bushings would be better quality than OEM RCF bushings.

[@auroravsat7215]

@@jackarnold5560 not much. About 340-350HP. Gotta do a lot of work to the engine to run more than that. Would recommend just getting one of the V8 Lexus. V6 is seem to be very under powered. Even with a tune. Traded it in for a M2 about a year ago.

[@GR8APE69]

​​​@@auroravsat7215 Correct me if I'm wrong, but I thought the IS 300 has the same drivetrain as the IS 200t, a 2.0L turbocharged inline 4 cylinder making ~250 HP at the crank. Getting 340-350 HP to the wheels out of bolt-ons and a tune is kind of insane and had to be pushing those internals to their limit, if not past it.

I hate bags only reason when they do end up ripping or have a hole in the bags you're vehicle will be stranded on the side of the road I've had a few bagged vehicles and would rather stick to coilovers. Running bags is better for car shows and driving it straight back home I've also been racing since the late 90's and racing a bagged car was not even a thought air shocks however I've seen on race cars before I think in the end it boils down to what do you plan to do with the car racing it showing it just cruising etc.

[@8742js]

Thanks for the great video. Really enjoyed it. I don't mind the stock settings for the most part with my IS, but you definitely inspired me to upgrade the front LCA bushings, do a full body wrap, get beefier wheels,,,, I noticed that the price gap is pretty big between the RCF/GSF bushings and the figs bushings. Where would you put the RCF/GSF bushings in between the stock IS bushings and the figs bushings (80 rating) in terms of ride quality and being able to alleviate inner tire wear?

[@Und3rgroundLex]

In terms of comparison both the RCF/GSF and FIGS will do the job to save the inner tire wear. The stocks will not. The difference really with the RCF/GSF and FIGS is really the ride quality you'll get once you install it. FIGS will feel more stiffer in terms of more better response in steering and etc. But if you want that OEM Style and still want that smooth ride with not too much of a change with stiffness, go with the RCF/GSF ones.
